unbound? -- Conf file?

I took the minimalist file from man unbound.conf, and the unbound-checkconf
and unbound itself does NOT like it:

# unbound-checkconf
/etc/unbound/unbound.conf:2: error: syntax error
read /etc/unbound/unbound.conf failed: 1 errors in configuration file
# ^D$
$ pwd
/home/ler
$ cat /etc/unbound/unbound.conf
        # unbound.conf(5) config file for unbound(8).
        server:
             directory: "/etc/unbound"
             username: unbound
             # make sure unbound can access entropy from inside the chroot.
             # e.g. on linux the use these commands (on BSD, devfs(8) is used):
             #      mount --bind -n /dev/random /etc/unbound/dev/random
             # and  mount --bind -n /dev/log /etc/unbound/dev/log
             chroot: "/etc/unbound"
             # logfile: "/etc/unbound/unbound.log"  #uncomment to use logfile.
             pidfile: "/etc/unbound/unbound.pid"
             # verbosity: 1      # uncomment and increase to get more logging.
             # listen on all interfaces, answer queries from the local subnet.
             interface: 0.0.0.0
             interface: ::0
             access-control: 10.0.0.0/8 allow
             access-control: 2001:DB8::/64 allow
$


So, what's the real problem, as the syntax error message is useless.

Thanks!
